Highly sensitive electrochemical sensor for tulobuterol detection based on facile graphene/Au nanowires modified glassy carbon electrode

Graphene/Au nanowire (G/Au NW) composites were prepared facilely by mixing well-dispersed graphene and Au nanowires and used to modify the glassy carbon electrodes as a tulobuterol electrochemical sensor. The modification activity of the composites was investigated with the electrochemical impedance spectroscopy technique. A sensitive, rapid and simple electrochemical method was developed for the detection of tulobuterol based on the strong enhancement effect of G/Au NWs. The peak currents varied linearly with the concentration of tulobuterol over the range from 7.6 x 10(-8) to 7.6 x 10(-8) mol L-1, and the detection limit was 1.36;: 10(-8) mol L-1 (SIN=3). The electrode developed can be used for the electroanalytical detection of tulobuterol and provide a potential application of tulobuterol in further research. (C) 2016 Elsevier B.V.
